Once I became familiar with the input it was pretty easy to use. However trying to Print was difficult. The on-line help didn't suggest using the DONE button!

The search option brought up the forms I needed. In on instance multiple versions were on different sites. I was able to bring in to the appropriate version by typing in the URL, I found that to be a real time saver.

Fan Bloody Tastic on my CHROMEBOOK, nearly real time and it would be 5 stars. Realtime not yet available in this part of Australia. PERFECT fit for 100% cloud and paperless. Love it, just re thinking it and it is now totally 5 stars. Thanks :)

Was a little cumbersome at first, but was able to figure out on own which says a lot about a computer program minus an instruction booklet. Yeah, I'm a little on the geek side.

Convenient, Affordable, Online PDF Editing & Mgmt Tool I use PDFfiller on a regular basis. The enhanced security options, including the ability to email a PDF to someone and that automatically includes a 'security code' for retrieval of the document gives me a sense of security since the actual document is not attached to the email, which could be intercepted if someone hacked into your mail server. I also use the merging tools, allowing me to combine multiple PDF's into one file, move pages, etc. It helps me to better organize my PDF libraries. Considering the other options of using a very high-priced service/product (Acrobat), PDFfiller is, in my opinion, a much better tool. I've been using 'PDFfiller', for the last 2 years. The editing tools available are great, including filling out forms, editing text, adding comments and signatures, makes it a very convenient to import and work with documents on-the-go. The ability to import/export to/from cloud-based sources as well as drag & drop. Import options makes things much easier in-terns of document management Honestly, there haven't been any tasks that I typically need to with PDF editing, etc. that PDFfiller already provide.

PDFfiller was easy to use. PDFfiller allowed me to edit and submit my application easily without much effort. PDFfiller allowed me to move the curser to start typing over the form questions. While this was not a hindrance it did take time to get the curser back to where it needed to be to complete the application. This small flaw was not enough to prevent me from using the application.
